This paper introduces the current world popular embedded Linux operating system, the latest ARM series chip and several digital sensors , such as temperature, humidity, light and so on, which are applied in the data acquisition terminal of the hospital environment intelligent monitoring system and used to monitor the environmental parameters of the hospital, such as temperature, humidity and light. Based on the embedded Linux operation system’s good portability and perfect support on I2C bus and GPIO and the ARM11 processor’s high efficiency and low consumption performance, a environment acquisition terminal is designed, which possess strong compatibility and low power consumption, and run well in practice. Keywords-data acquisition; ARM11; Linux kernel module; I2C; GPIO; environment sensor
